SEAT ATTACHMENT FOR WATER-CLOSETS SPECIFICATION forming part of LettersPatent No. 524,516, dated August 14, 1894. Application filed February17. 1894. Serial No. 500,539. (No model.)

To all whom t may concern/.-

Be it known that I, JOHN H. STEvENs, J r., of Cambridge,in the county ofMiddlesex and State of Massachusetts, have invented certain new anduseful Improvements in Seat Attach- `ments for Water-Closets, ofwhichthe following, taken in connection with the accompanying drawings,is a specification.

My invention relates to seat attachments for water closets and itconsists in certain novel features of construction, arrangement andcombination of parts which will be readily understood by reference tothe accompanying drawings and to the claims hereto appended and in whichmy invention is clearly pointed out.

My invention is designed especially for use in connection with watercloset bowls that are not inclosed, but stand out from the wall and areexposed to view, and is clearly illustrated in the accompanyingdrawings, in which- Figure l is a side elevation of a water closet bowlwith my invention applied thereto. Fig. 2 is a plan of same with a smallportion of the seat cut in section in order to more clearlyillustratethe manner of connecting the metal hinge to the seat. Fig. 3 is asection through the hinge and a portion of the seat on line no, as, onFig. 2. Fig. 4 is a partial sectional plan ofthe hinge detached from theseat, the cut-ting plane being on line y y on Fig. 3. Fig. 5 is asectional elevation of one of the brackets and the mechanism foroperatingthe discharge valvein the flushing tank, not shown, and Fig. 6is a similar View illustrating the application of my invention to theoperation of said Valve by a flexible connection instead of a rod.

In the drawings A is the closet bowl of porcelain or any other suitablematerial and made of any desired form, and provided with any suitablemeans of supplying flushing water thereto.

B is,the seat made of wood and provided with the usual rubber lugs orcushions a, a, set in its under side so as to bear upon the uppersurface of the rim of the bowl when the seat is occupied.

C and C are two brackets secured by suitable screws to the wall of theroom, and provided with perforated hubs b and .b to receive therearwardly projecting arms c, c', respectively, of the fixed portion ofthe hinge, said rods or arms c c' being adjustably secured in said hubsby the nuts b2, or in any well known manner, for the purpose of varyingthe distance from the wall of the room to the center of the hinge. I v

Therods or arms c, c', are screwed into the quarter turns ol, drespectively and said quarter turns are connected together by the pintlerod c which passes through the sleeve D of the movable part of thehinge, and is screwed into said quarter turns. The sleeve D is formed tofit the curved rear-'edge of the seat B and has formed integraltherewith the two rods or arms g, g, which project at right angles tothe axis of said sleeve and parallel to each other and are tted intoholes bored into the seat B and are secured therein by screws h 7?.passing through said arms and screwing into the wood of the seat asshown in Fig. 2.

The rear edge of the seat B is grooved so as to partially surround thecentral portion of the sleeve D while the two end portions of the sleeveare expanded on curved lines to conform to the shape of the contiguousportions of the seat edge as shown in Figs. 2, 8, and 4, and the innerfaces of said curved end portions of the sleeve are made concave asshown in Fig. 4 to the better conform to the shape of the seat. Thesleeve D also has formed thereon a hollow boss projecting toward therear into which is screwed the arm j so as to form in connection withthe seat a lever to operate the discharge valve in the tank.

The arms c, c', g, g', and j are preferably made tubular in order toreduce the weight of the parts but they may be made solid if desiredwithout aifecting the principles of my invention.

The bracket C has formed therewith, or secured thereto, the three armedtie-plate C2 to which is pivoted the lever E, in position to be actedupon by the armj to move it about its fulcrum when the front of the seatis depressed by a person sitting thereon.

The leverE may be pivoted by one end to the plate G2, be connected atits other end to one of the ends of the rod F, the other end of which isconnected to the valve operating lever (not shown) in a wellknowumanner, and the army be arranged toact upon said lever between itsfnlcrum and its connection with the rod F, as shown in Fig. 5, or thefulcrum of said lever E may be between its two ends, be connected at oneend to a chain or other flexible connection extending therefrom to thevalve lever, (not shown) and the arm.)l act upon said lever E at or nearits other end, as shown in Fig. 6.

The parts at the rear of the center of the hinge are to be constructedor weighted so as to slightly overbalance the weight of the seat in sucha manner that when the seat is unoccupied its front will be slightlyraised, as shown in Fig. 1. By this construction avery strong connectionof the hinge to the seat is obtained which will not easily get out oforder, and a strong rigid lever is obtained for operating the flushingvalve, with very little additional cost and without disfiguring theseat, or the expense of a bracket at the side of the bowl to hang thevalve operating lever upon, as heretofore practiced, but which detractsmaterially frorn the appearance of the closet.

The armyl may be screwed into the boss i as shown or it may be castintegral with the sleeve or hinge section D if preferred withoutaffecting the principles of my invention.

What I claim as new, and desire t0 secure by Letters Patent of theUnited States, is-

1. In a water closet the-combination with the closet bowl of a pairofbrackets secured to the wall of the room and connected together by ahinge pintleat right angles thereto; the closet seat provided with twoholes or sockets extending' from its rear side toward the front edgethereof and parallel to each other; and a sleeve surrounding said pintleand provided with two arms extending at right angles therefrom andinserted in said sockets in the seat and secured therein.

2. The combination of a water-closetseat provided with parallelV socketsextending thereinto from its rear edge; a hinge sleeve provided with twoparallel arms extending therefrom at right angles to the axis of saidsleeve and firmly secured within said sockets; a third arm extendingfrom the opposite side of said sleeve; a pintle extending through saidsleeve; a pair of parallel arms secured to opposite fends of said pintleand a pair of brackets secured to the wall of a room and provided withbearings or sockets to receive said arms; a lever mounted on a lfixedfulcrum in position to be acted upon by the arm projecting from the rearof said sleeve to move it about its fulcrum; and a connection extendingfrom said lever to the flushing 6o Valve or a lever connected thereto.

3. In a water closet, th combination with the closet bowl of a pair ofsupports or bearings secured to the wall orf'other fixed portion ofthebuilding; a hinge pintle or shaft contending at right angles therefrominto said 7o lsocket and secured therein, and another arm formed upon orsecured to said sleeve and projecting to the rear thereof as and for thepurposes described.

4. The combination of a movable watercloset seat; a revoluble section ofa hinge firmly secured to and movable with said seat and provided with arearwardly projecting arm; a pair of brackets or stands secured to thewall or other fixed portion of the building 8o and pivotally connectedat their front ends to the portion of the hinge that is secured to theseat; a lever mounted upon a fixed fulcrum in position to be acted uponby the end of the arm which projects from the rear of the seat sectionof the hinge; and a connection extending from said lever for operatingthe flushing valve.

5. The combination of a movable water closet seat; a hinge sectionfirmly secured to 9o port or bearing for said seat hinge; a levermounted upon a fixed fulcrum in position to be acted directly upon bysaid rearwardly projecting arm but disconnected therefrom; and aconnection operated by said lever for controlling the iiushing valve.

6. The combination of the seat B having two parallel holes bored thereinfrom its rear edge and extending toward` its front; the* hinge section Dprovided with the two parallel arms g, g', extending therefrom into theholes in said seat and Asecured therein; a fixed or non-revolublesupport for said hinge section; and the arm j firmly secured to saidhingesection and movable therewith as a means of operating the ushingvalve.

K In testimony whereof I have signed my name to this specification, inthe presence of two subscribing witnesses, on this 14th day ofFebruary,A. D. 1894.
